IOException이 : SSL 컨텍스트를 초기화 할 수 없습니다 - 아파치 코 몬즈 넷 - 나는 아파치 FTPSClient를 사용하여 FTP에 연결을 시도하고 있지만이 오류가 계속

Question

안드로이드 :

9월 6일에서 15일까지 : 15 : 14.749을 : W를/System.err (29451) : java.io.IOException : SSL 컨텍스트를 초기화 할 수 없습니다.

이 오류는 다음 코드와 함께 발생하며 두 번째 줄 (연결)에 나타납니다.

ftpsClient = new FTPSClient("SSL"); 
ftpsClient.connect(host); 
int reply = ftpsClient.getReplyCode(); 
if(!FTPReply.isPositiveCompletion(reply)) { 
    ftpsClient.disconnect(); 
} 
ftpsClient.login(user, password + nl); 
ftpsClient.setFileType(FTP.BINARY_FILE_TYPE); 
ftpsClient.enterLocalPassiveMode(); 

내가 잘못하고있는 것에 대한 제안이 있으십니까?

Answer 1

와 예외 . 수동으로 기본값을 설치하십시오. 다음과 같음 :

KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm()); 
kmf.init(null, null); 
KeyManager km = kmf.getKeyManagers()[0]; 

ftpsClient = new FTPSClient("SSL"); 
ftpsClient.setKeyManager(km);
